There's nothing wrong with managed switches, generally. I've run LTSP on quite a few brands over the years, and I love 'em.
One key factor is spanning-tree negotiation. Normally the spanning-tree algorithm will take about 30 seconds to bring up a port. It's usually necessary to turn on what is generically called "Rapid Spanning Tree". Some vendors call it "fast-learning" or "portfast" or something similar. Apple Macintoshes, including those running OS X, also required this back when we still had some of those.
Now, all that said, I doubt very seriously that this is a switch issue. The reason is that you told us you can get 50 clients running just fine. Ethernet switches actually don't give a rip if your traffic's even TCP/IP. They only care that your frames have the proper 802.3 Ethernet header, and however many frames there are doesn't matter, up to the capacity of the switch's backplane. The fact that you had K12LTSP 5EL working just fine on it before tells me it ain't the switch.
